Abstract
In a method for preparing a luminescent screen which includes depositing a light-absorbing matrix upon a support, depositing a phosphor-particle layer on the matrix and support, and then coating the phosphor-particle layer with a film of organic polymeric material, the steps for salvaging the support and matrix substantially undisturbed, while substantially entirely removing the overlying material. In the method, the overlying material is contacted with an alkaline aqueous solution until the organic polymeric film is at least partially solubilized. Then, the overlying material is substantially entirely flushed away.
